I agree with the last two posts. I live in a condo and run my HT through a CLS 9900 amp and a CLS 9600 ISO and find the difference significant. The background is quieter, and the bass tighter. I've also found the sound better when running my amps through these as opposed to the wall outlets (I use five of then). I found this to be true with my bedroom system as well. As far as I can tell, unless you can run dedicated lines with isolated star grounds (unquestionably the best setup) you will find benefit from power conditioning. Just be careful, some limit the power to amps and will restrict their power (thus the 9900 amp in my system).
I've not used the ESP, but love my Chang's, in fact I''ll be buying another soon.....
